- `istio-cni`
    - CNI plugin executable copied to `/opt/cni/bin`
    - currently implemented for k8s only
    - on pod add, determines whether pod should have netns setup to redirect to Istio proxy. See [cmdAdd](#cmdadd-workflow) for detailed logic.
        - it connects to K8S using the kubeconfig and JWT token copied from install-cni to get Pod and Namespace. Since this is a short-running command, each invocation creates a new connection.
